Every possible buyer of an immaterial pictorial sensitivity zone must realize that the fact that he accepts a receipt for the price which he has payed takes away all authentic immaterial value from the work, although it is in his possession.

..the thinking man is no longer the center of the universe, but the universe is the center of the man [referring to collaborations between artists, in which Klein was involved several times]. We shall then know 'prestige' in comparison to the 'vertigo' of before. Thus we shall become men of the air, we shall know the upward force of attraction, towards space, towards nowhere and everywhere at once; having thus mastered the earthly force of attraction we shall literally levitate in complete physical and spiritual freedom.

I remain detached and distant, but it is under my eyes and my orders that the work of art must create itself [Klein directed on 9 March 1960 for the first time nude models who were painting the walls with their moving naked bodies, he called this "Anthropometry"]. Then, when the creation starts, I stand there, present at the ceremony, immaculate, calm, relaxed, perfectly aware of what is going on and ready to welcome the work of art that is coming into existence in the tangible world.. .Hours of preparation for something that is executed, with extreme precision, in a few minutes. Just as with a judo throw.
